Talking a walk down memory lane, Ramos, who claimed the UEFA's prize for the best defender in the 2017/18 Champions League campaign, on Thursday, recalled how Ronaldo informed his Los Blancos teammates that he was leaving the Santiago Bernabeu dwellers.

The awards were only a sideshow at the event compared to the Champions League draw, as Juventus were drawn against Ronaldo's former club Manchester United as well as Valencia and Swiss champions Young Boys. They have done a very good job over the past few years, so it won't be easy.
Teams from the same country could not be drawn together Thursday, and teams from Ukraine and Russian Federation were also kept apart due to ongoing political tensions.
"I always try to improve on what I did the previous season, because matching what Messi and Cristiano do by scoring 50 to 60 goals a year is very hard. They're on a different level".
